The corrugated cardboard used is a paper-based material with a relatively high strength. Based on several rounds of tests in the factory and the previous design practices of Cardboard-formed Exhibition Space 1.0 and 2.0, it has been confirmed that this material can be repeatedly assembled, disassembled and reassembled many times, thus realizing long-term and repeated reuse. It is conceivable that the two “paper houses” can also be dismantled after the exhibition and can achieve sustainable reuse as well like its predecessors.
